It's implicit - but my criticism here is mostly that once you know one development stack learning others is significantly easier.
Learning Java is something that a backend developer can likely do in a week - and so is learning Node.js after knowing Java.
- ctvo 8y agoKnowledge of a language is a scale and not a binary yes / no question. Being passingly familiar with a language is a week exercise, putting it on your resume / CV and saying you're ready to write production quality code is different. For Java specifically: - How does the JVM memory model and other internals work? - How comfortable am I with the standard library? - What are the idioms and design patterns used by professionals in Java? - Performance pitfalls that are tribal knowledge with concurrency / threading, etc? If the scale of language knowledge is 0-10, getting to 3, where you're familiar with the syntax, common language features and a few APIs is a week's exercise after you've used a few languages (in the same family -- I'm not going to be passingly familiar with Haskell in a week).
